Flashcards

First Generation Computers

Early computers that used vacuum tubes, were large, expensive, and programmed in machine language.

Second Generation Computers

Computers that used transistors instead of vacuum tubes, enabling more efficient programming using assembly and high-level languages.

Third Generation Computers

Computers using Integrated Circuits (ICs), smaller and more efficient than earlier generations. Programs could be run using punched cards or printers.

Computer Components

A computer is made up of many parts working together.

Study Notes

Computer Generations

First Generation (1940s-1950s): Vacuum tube computers
- Used punched cards for input
- Large and expensive
- Consumed a lot of power
- Programming was done in machine language
Second Generation (1950s-1960s): Transistor computers
- Used transistors
- Assemble language and high level programming languages
- Used magnetic core memory for storage
- Input methods included punched cards and other input devices
Third Generation (1960s-1970s): Integrated circuit (IC) computers
- Integrated circuits (ICs)
- More reliable and compact
- More affordable
- Wider variety of input and output devices
